Description
Technical field
The present invention relates to a kind of zipper strip feed unit that can be applicable to the continuous manufacturing apparatus of fastener stringer, this continuous manufacturing apparatus is used for the engaged element that is used for slide fastener is appended to the zipper strip of interrupted supply, wherein, slide fastener obtains by cut off the engaged element wire rod that has by the multistage rolling cardinal principle y-shaped cross-section that forms on the direction of the lateral cross section of slide fastener.
Background technology
For this engaged element that is used for slide fastener, the long metal wire rod with circular cross-section forms the lateral cross section of Y shape substantially by a plurality of rolls, and is cut into predetermined thickness to obtain each engaged element material with cutting off drift and cutting off mold in turn.Then, the engaged element head forms mountain shape shape to obtain engaged element (hereinafter being called the engaged element that wire rod is made) with forming punch and shaping dies.The manufacturing process that is used for the engaged element that a kind of like this wire rod makes has been disclosed in for example EP-A-0028358.In the engaged element after finishing this shaping, its additional leg is hammered clamping into shape with clamping, and appends to the predetermined pitch order on the engaged element extention of zipper strip.
Thereby, for example be provided with the step feed part by the disclosed conventional zipper band of Japanese publication No.S59-51813 feed unit, when finishing the shaping of engaged element, this step feed partly is used for above-mentioned pitch zipper strip being fed into intermittently the downstream of engaged element extention.Yet when engaged element appended on the zipper strip continuously, even zipper strip is to equate pitch feeding intermittently, engaged element can not be to equate that pitch appends on the zipper strip.Reason according to routine, when interrupting the supply of zipper strip, importantly, applies predetermined tension and tension force is remained on steady state value for the zipper strip in step feed upstream partly for this reason.In order to keep constant tension force, as routine was done, zipper strip also led with being arranged in the elastic guide spare that transports on the passage that is used for zipper strip, is absorbed the variation of the tension force of zipper strip thus by spring force.Perhaps, the so-called dancer roll with predetermined weight is placed on the zipper strip, thereby it freely moves up and down according to the weight of roller.And the feed rolls part of rotating with constant speed can be arranged in the upstream side of zipper strip with respect to dancer roll.
Explanation in passing, the zipper strip of supplying with continuously when the manufacturing of fastener stringer is extremely long, and the band feed unit usually continuously operation for a long time, for example once several hours to tens hours.On the other hand, zipper strip generally is made of textile fabric or knit goods, and does not run through the assurance fully uniformly of whole length quality.Moreover its physical property may change owing to humidity and Temperature Influence.In addition, the common integral body of heart yearn appends to and is used on the engaged element extention of zipper strip of the engaged element that additional wire rod makes.Thereby the part place of the heart yearn that the rugosity of heart yearn is added having adds on the thickness of zipper strip itself, causes partly that by feed rolls part and step feed the sensitivity of zipper strip feed speed changes thus.And the amount of feeding of zipper strip is also by changing sensitively by the sliding influence of for example partly locating at feed rolls.
Although the variation of the amount of feeding is not too big, rise to great changes by operating in for a long time in the very big total length, thereby for example belt tension increases gradually during operation, surpass the weight of dancer roll thus.Selectively, increase gradually, and last zipper strip is lax between feed rolls part and step feed part, and does not support dancer roll from the feed rolls amount of feeding partly.As a result, zipper strip is sedimentation there, and becomes impossible as the tension adjustment of initial purpose, causes inevitably thus stopping to make.
Summary of the invention
Realized that the present invention is to solve a kind of like this problem, and the objective of the invention is to, a kind of zipper strip feed unit is provided in the fastener stringer continuous manufacturing apparatus, tension force at the zipper strip of engaged element appendix office in this zipper strip feed unit can automatically be regulated in the predetermined tension scope all the time, and the engaged element that this fastener stringer continuous manufacturing apparatus is synchronously made the wire rod of interrupted production appends on the zipper strip of interrupted supply.
To achieve these goals, the invention provides a kind of zipper strip feed unit that is used for the continuous manufacturing apparatus of fastener stringer, this continuous manufacturing apparatus appends to the zipper strip that intermittently supplies to retained part with predetermined pitch to the additional leg of the engaged element that is used for slide fastener successively, after the wherein interrupted metal wire rod of supplying with cardinal principle y-shaped cross-section cuts off by the form of orthogonal, it is formed chevron and obtains additional leg, and this zipper strip feed unit comprises: the zipper strip supply source; The feed rolls part is used for determining and feeding zipper strip continuously from supply source; Dancer roll, it is hung by the zipper strip of continuous feed between feed rolls part and engaged element implant part, and moves up and down corresponding to the variation of belt tension; The step feed part, it is arranged in the downstream of the zipper strip of engaged element implant part, and feeding zipper strip intermittently; Sniffer is used for surveying the upper limit of movement position of dancer roll and the lower position of moving; And control section, when detection arrives upper limit of movement position and motion lower position to dancer roll or when detection breaks away from by upper limit of movement position and motion lower position restricted portion to dancer roll, be used for controlling the band amount of feeding of feed rolls part, thereby dancer roll is remained in this scope based on detectable signal, wherein, one end of tilting member is supported on the place, fixed position with axle journal, and dancer roll supports through back shaft rotationally at the other end place of this tilting member; And sniffer comprises the rotary encoder at an end place that is arranged in above-mentioned tilting member.
Stand with the interrupted metal wire rod of supplying with that is used to have the engaged element of wishing the cross section of predetermined pitch multistage rolling to form all smooth cardinal principle y-shaped cross-sections, then, wire rod upwards supply with intermittently one with the corresponding amount of single engaged element.When finishing the feeding of wire rod, wire rod is from cutting off the outstanding corresponding length of thickness with single engaged element of mould.Then, cut off mould and begin to retreat, the ledge of wire rod cuts off with cutting off drift, and engaged element is from cutting off mould to the shaping dies motion in the rear end rest position of cutting off mould.At this moment, the clamping hammer is under the halted state, and shaping dies is from the additional leg of supported on both sides engaged element, to adjust the horizontal movement of engaged element.
After this, when the shaping drift reduces, also reduce a pressure pad, thereby engagement post is formed mountain shape form.Then, cut off mould and shaping dies and advance synergistically, then, a pair of right side and left clamping drift begin operation, thereby therefore the additional leg of engaged element and is out of shape on approximating direction by the clamping face clamping that is formed on the clamping drift.Be affixed on the engaged element extention of zipper strip of interrupted supply and after remaining under the stand-by state, the step feed unit activated at engaged element, thereby the next engaged element extention of zipper strip is fed into the retained part of clamping drift.On the other hand, zipper strip is from the feed rolls feeding continuously of the upstream that is arranged in zipper strip.At this moment the amount of the zipper strip that goes out from the feeding of feed rolls part is set in advance, and the driven roller of feed rolls part rotates with constant speed, with the constant amount of zipper strip feeding.
Yet, because zipper strip is made of textile fabric or knit goods usually, so it can not be made in a kind of so whole length of long zipper strip fully equably.And the physical property of such zipper strip may change according to surrounding working environment, and in addition, heart yearn by make, braiding or knitting engaged element extention along zipper strip be by additional, the engaged element made from the assembling wire rod.And zipper strip is contained in the jar usually, thus it reel with volution, and by feed rolls part by pull-ups definitely such as guides, and be fed into the step feed part.Dancer roll is inserted in the feed rolls part and is interrupted between the feeding part, thereby the tension force of zipper strip is remained under the steady state value.When zipper strip was pulled out from wherein be contained in the state the jar as described above with volution under, the band of pulling out usually twisted.
The velocity variations of the zipper strip that goes out from the feeding of feed rolls part, because of slippage occurs in the feed rolls part, zipper strip is fed into the feed rolls part with twisted state, perhaps zipper strip since the combination of such various factors prolong or shrink.If, and only just can sufficiently regulate usually with dancer roll because the tension variation that causes of this velocity variations observes at short notice then be minimum.Yet, if feed unit is operated slight for a long time variation accumulation continuously, thus bringing into when feeding is initial to deflecting into a side.As a result, though with the weight of dancer roll adjustment of tonicity accordingly, tension force can not remain on steady state value.And, even physical property causes the variation from the amount of feeding of feed rolls part thus usually according to changing in operation period or the zipper strip that adopts the zipper strip of identical type also to make under different condition.
Thereby, according to the present invention, as described above, positional detecting device is arranged in the position that moves up and down of dancer roll, and when its probe value reaches the upper limit or the lower limit of the position that moves up and down or breaks away from the upper limit or following prescribing a time limit, signal sends to feed rolls drive part partly by control section, controls the velocity of rotation of driven roller thus.For example, when dancer roll surpassed its upper limit position, the amount of feeding of zipper strip was increased by the velocity of rotation of rising driven roller.When the dancer roll motion was below the lower position, the amount of feeding of zipper strip was reduced by the velocity of rotation that reduces driven roller.As a result, the belt tension total energy between step feed part and feed rolls part keeps constant, particularly when adding when wherein stopping the engaged element of zipper strip, even continued operation also is like this for a long time.If guarantee by this way the tension force of zipper strip to be remained steady state value at the additional hours of engaged element, then make the additional spacer (pitch) of engaged element even, obtain the high-quality fastener stringer thus.
About sniffer, for example, can use limit switch or photoelectric tube.Yet, preferably, rotary encoder is installed on the near-end of swing of swing arm as described above, and the hunting range of dancer roll that is supported on the front end place of swing arm rotationally surveyed by rotary encoder, and its detectable signal sends to control section.Therefore, mechanical movement can convert the signal of telecommunication reliably to, and is extremely accurate thereby the transmission of durability that improves equipment and signal becomes, and improves the reliability of detection accuracy and further control accuracy thus.

Zipper strip T is led by the first and second guide roller 35a, 35b from zipper strip supply source (not shown), and pulls out between driven roller 36 and pressure roll 37 in the feed rolls part with being determined.At this moment, driven roller 36 rotates with constant speed, and the dancer roll of describing later on 38 swings up and down in predetermined hunting range simultaneously.For example, servo motor 39 is used for driving driven roller 36.On the other hand, whenever engaged element when the 3rd to the 6th guide roller 35c to 35f by being arranged in the band downstream is by the tape guiding piece in the engaged element implant part 16 guiding by additional hours, zipper strip T is by interrupted driven roller 17 and pressure roll 18 pull-ups in the step feed part.Then, a fastener stringer S who finishes is fed to next process.
On the other hand, usually, its above-mentioned fastener stringer manufacturing equipment of using zipper strip feed unit of the present invention was operated tens hours continuously.Thereby zipper strip T also supplies with the identical time period continuously.Zipper strip T is made of textile fabric.Even carry out quality control,, comprise that then the zipper strip T of textile also changes easily in uniformity and stretching, extension aspect of performance if ambient conditions changes about hardness.And, for the engaged element E that above-mentioned wire rod is made by clamping appends on the zipper strip T, than be used in the thick heart yearn of warp among the zipper strip T and parallel along the engaged element extention fix or when braiding or the banding in by braiding or knitting fixing.
Even for example the velocity of rotation of driven roller 36 is constant, but by receiving other influence of the thickness difference on the bandwidth direction that causes by the slippage between roller and heart yearn position, the amount of feeding with zipper strip T of a kind of like this feature also changes, although change just very little.Continuous long zipper strip T holds to become, it in the container such as jar with the volution afterturn.When the zipper strip T in being contained in this jar was drawn out jar, distortion may take place.If the feed rolls part is taken in this distortion to, its amount of feeding is subjected to very big the influence.If although observe the variation of the amount of feeding at short notice is not very big, become very big variable quantity behind these after continued operation tens hours or one day, influence the tension force of zipper strip T thus.Therefore, change the additional spacer (pitch) between engaged element, and continued operation was lost efficacy.
According to this embodiment, when predetermined angle position (the position P2 of Fig. 3) supposition of rotary encoder 40 was reference position 0 ,+α ° angle location definition was upper limit position (the position P1 of Fig. 3), and-α ° angle location definition is lower position (the position P3 of Fig. 3).In this case, when dancer roll 38+α ° and-α ° between the time, do not have output signal to send to servo motor 39.If the center of dancer roll 38 is higher than+α °, and then signal for faster outputs to servo motor 39, thus servo motor 39 is accelerated to the velocity of rotation that sets in advance, so that partly increase the amount of feeding of zipper strip T by feed rolls.In addition, if the center of dancer roll 38 drop to-α ° below, then reduce-speed sign outputs to servo motor 39, thus servo motor 39 is decelerated to the velocity of rotation that sets in advance so that partly reduce the amount of feeding of zipper strip T by feed rolls.
When the angle that moves up and down of dancer roll 38 is outer to+α ° to-α ° predetermined angle scope, the velocity of rotation by control driven roller 36 is arranged on dancer roll 38+α ° extremely-the predetermined angle scope of α ° in.Thereby, can be set to constant all the time in feed rolls part that is used for zipper strip T and the tension force that is interrupted between the feeding partly.Therefore, produce high-quality fastener stringer S, make the high-quality slide fastener thus.
